176449-09 BENTLY 3500/42M Proximitor Seismic Monitor

Description 176449-09 BENTLY 3500/42M Proximitor Seismic Monitor Product Dimensions： Product Description (Detailed Explanation) The 3500/42M (represented by part number 176449-09) is a high-performance monitor designed to protect critical rotating machinery by measuring both radial vibration and casing vibration. Unlike standard monitors, the “M” designation (Proximitor Seismic) indicates its versatility: it can process signals from proximity probes to measure shaft motion, or from seismic sensors to measure absolute housing vibration. The module continuously compares measured parameters against programmed alarm setpoints. If a value exceeds these limits, the monitor drives alarms and can trigger executive credit through the 3500 system relay modules to shut down the machine, preventing catastrophic failure. Product Parameters (Technical Specifications) Parameter Category Specification Input Channels 4 Channels (Independently programmable) Signal Inputs Proximitor, Accelerometer, Velocity Transducer Power Consumption 7.7 Watts (Typical) Accuracy $\pm$ 0.33% of full-scale typical Frequency Response 0.5 Hz to 30 kHz (Sensor dependent) Resolution 0.1% of full-scale Buffered Outputs 4 Coaxial connectors on front panel (one per channel) A/D Conversion 24-bit Sigma-Delta Operating Temp. $-30^{\circ}C$ to $ 65^{\circ}C$ Mounting Standard 3500 Rack (Full-height slot) Product Advantages (Key Benefits) Dual-Functionality: Eliminates the need for separate modules for shaft and casing vibration, reducing spare parts inventory and rack space requirements. Continuous Monitoring: Provides 24/7 protection with high-speed processing, ensuring that even rapid “spike” events are captured and acted upon. HART Compatibility: Supports digital communication for enhanced diagnostics and sensor health monitoring when used with compatible transducers. High Reliability: Designed for “Mission Critical” applications; includes extensive internal self-tests (Software/Hardware Watchdogs) to ensure the monitor itself is healthy. Front Panel Access: Features dedicated buffered outputs for each channel, allowing vibration technicians to connect portable analyzers (like the Scout or ADRE system) without interrupting the protection loop. Precautions (Important Notes) Configuration Requirement: The module must be configured using the 3500 Rack Configuration Software. It will not function until the correct transducer scales and alarm setpoints are downloaded to the rack. Grounding: Ensure the sensor shields are grounded only at the 3500 rack end (unless using an isolated mounting) to prevent ground loops that cause “noise” in the vibration data. Hot-Swapping: While the 3500 system supports hot-swapping, it is critical to ensure that the machine is not in a critical state or that trip-multiplied relays are bypassed to avoid accidental shutdowns during the swap. Cable Lengths: Observe maximum cable length limitations for Proximitor sensors (typically 5m or 9m) to maintain signal calibration accuracy. Product Applications (Typical Use Cases) Steam & Gas Turbines: Measuring radial vibration (shaft-to-bearing) and casing velocity simultaneously to detect imbalance or misalignment. Centrifugal Compressors: Monitoring high-frequency vibration to detect early signs of impeller damage or surge conditions. Large Pumps & Fans: Providing basic protection against bearing wear and mechanical looseness in balance-of-plant equipment. Gearboxes: Utilizing the high-frequency range of accelerometers to detect gear tooth pitting or cracking. Hydroelectric Generators: Measuring low-frequency shaft vibration where absolute and relative measurements must be correlated.
